Old Timer!..Back at it!..am i missing anything? PLEASE HELP

So Ive had a year layoff...But im back at it...Im Doing DWC in 5 gallon buckets..So heres what i have..and i need you guys to tell me if im missing any key components..TAKE IT EASY..ITS BEEN AWHILE lol
1) 4x4x6 foot tent
2) Sun Master II 4" Reflector (1000w HPS+MH)
3) 5-way Air Pump (951 gph / 3.48 psi) Airstones etc.
4) Canna Aqua Vega and Aqua Flores for the nutrients
5) Intake fan in the tent with duct connected to outside...(pulling air in from the outside)
and the outtake fan is hanging in the tent blowing air into the room (no duct)

I have all the basics...I believe...few questions...PLEASE HELP EXPERIENCED DWC'ERS!
1) Any tips on where I can get cheap tempered glass? I have had heat problems in the tent with a 1000watter and no glass...
2) Can i use Superthrive in DWC?
3) Also can i mix AN Bud Candy in with the other nutrients?
4) If i have 2 airstones(4" tall circular) in ONE 5 gallon bucket is that 2 much air?

I will have more ?'s im sure...

THANKS FOR ANY HELP IM ABOUT 2 RECEIVE IN ADVANCED!!!

Superthrive is "snake oil" period!
The AN product Bud Candy is not very effective as it's too watered down to make much difference.
You can make a product on your own that works about better then any store bought one! For about a dollar a gallon!

Add a Ca/Mg to your list and use it !
You never get "too much" air.....Look at the circular flat stones = good stuff!
Consider using Silica......Be aware of the special mixing needs of Silica use!

Nice..I will take all of that info!
So superthrive sucks in DWC?

And what else would I need to mix Silica into my buckets Doc?
Im using Canna Aqua Vega and Canna Aqua Flores..
Buy some Cal-Mag...Buy some flat air stones..And what else for the Silica?
THANKS DOC AND ANYONE ELSE WHO CAN HELP!
